.PLATE-l-IOLDER Foa CAMERAS.

SPECIFICATION forming part of Letters Patent No. 248,175, dated. October 11, 1881.

f Application led July 9, 1881. (No model.)

To all 'whom it may concern:

Be it known that I, AUGUST HERZOG, of Guttenburg, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Plate-Holders for Cameras, ot' which the following is a specification.

This invention has reference to an im proved plate-holder, which is arranged to hold two dry plates and frames, the plates being separated by a removable septum.

Theinvention consi sts of aplate-holder made of two hinged and locked sections, each of which is provided with square corner-guides, and with supports'intermediately between the guides for the frames. The sections are separated by a septum, which is secured to guidepins ot' one of the sections and tightly tted to both sections by raised middle portions. Each section is closed bya sliding cover, which is arranged flush with the exterior surface of the section, and provided with a projecting tongue at the inner edge,whieh lits into acorrespondinggroove of the section, so as to tightly close each section against the entrance of rays.

In the accompanying drawings, Figure l represents a side view of my improved plate-holder. Fig. 2 is an end view; Fig. 3, a vertical transverse section on line aux, Fig. 1; Fig. 4, an elevation of the plate-holder, shown in open position, and Fig. 5 is a horizontal section ot' the same on line y y, Fig. l.

Similar letters ot' reference indicate corresponding parts.

The frame of the plate holder iscoinposed of two sections, AA, which are hinged together at one end and connected by a suitable lock at the opposite end. Between the sections A A is introduced a detachable septum, B, which is secured by holes to pins c ot' one section A, said pins registering with socket holes c ot' the other section A. Each section A of the plate -holder is provided at the inside with corner-guides d, of square shape, and interme- 4diately between the same with shoulders or staples e, for the support of the frame C, which may be placed either in line with the longitudinal axis of the plate holder or in a position at right angles thereto, according as landscapes or portraits are desired to be taken by the photographic apparatus. This simple arrangement enlarges the application ot` the plate holder and renders it more convenientt'or practical use. The corner guides d and frames C are somewhat below the inner surface ot' each section A, so as to provide space for the middle raised portion ofthe septum B, which is thereby closely iitted into each section.

The septum B is provided at both sides with the usual springs, which bear on the plates and hold them in position in the frames. Each section is furthermore provided with a sliding cover, E, which is made Hush with the exterior surface of the section, and guided by side tongues in grooves ol' the sections. Theinner edge ofthe sliding coverE is itted bya tongue, b, into a corresponding end groove ofthe section, so as to prevent the passage of rays to the inside ot' the plate-holder. The outer edge ot' each cover E is provided with a shoulder, d, and with a button, d', for drawing out and pushing in the cover. The outside ot' each cover E is furthermore provided near its inner edge with a transverse elastic strip, c, of velvet or other suitable material, by which the plate-holder presses against the frame ot' the camera, so as to shut out any rays ot' light therefrom.

The advantages of my plate-holder are, that two dry sensitized plates and two frames for holding the same can readily be inserted into each section of the holder, and can be carried therein for successive use.

Having thus described my invention,I claim as new and desire to secure by Letters Pat ent- 1. In a plate-holder for cameras, the combination, with hinged sections A, of an interme diate removable septum, B, which is tted by raised center portions into the sections and secured in position between the hinged sections, substantially as and for the purpose set forth.

2. In a plate-holder for cameras, the combiV nation ot' hinged sections A A with an-intermediate removable septum, B, which is fitted by raised center portions into the sections and secured to guide-pins of one section, substantially as specified.

3. In a plate-holder for cameras, the combi IOO nation, with the hinged sections A and an intermediate removable septum, B, fitted thereto, with sliding covers E, which are arranged flush with the exterior surface of the sections, substantially as and for the purpose set forth.

4. In a plate-holder for cameras, the hinged Sections A A, having sliding covers E, Hush with the outer surface of the same, .rnd provided with exterior elastic bands or strips e near the inner edges of the sections, snbstanro tinily es described.

In testimony that I claim the foregoing as my invention I have signed lny naine, in presence of' two witnesses, this 7th dayofJuly, 1881.

AUGUST HERZOG.
